aspnetcore: Oauth2 authentication erroring with "The oauth state was missing or invalid."

I’m trying to use app.UseOAuthAuthentication(), however it seems to be having issues with the system I’m integrating with.

They have a system where links are clicked in their portal and users are directed to my application with the code already in-hand. I think in this sense, I’m beginning the oauth2 flow somewhat half way through, although it still abides by standards.

Is there any way to tell the middleware to not require a state parameter or is this something that needs to be added as an optional feature?
